In my opinion, he was an ambiguous guy at best who just happened to be on the right side. The 'prank' I mentioned at the absolute least confirmed Lupin's heavily stigmatized condition to a known bigot, and can you even imagine how he would have felt the next day if he had killed someone? Or even just passed on his life-ruining lycanthropy? It was an evil thing to do no matter how you look at it.

And that's not even mentioning his treatment of the mentally-ill family slave.

I absolutely hated Arvo from TellTale's The Walking Dead. That dick ended up shooting an eleven-year old no matter what. Even if you let him keep his medicine or sympathise with him after the shootout. Just because you protected yourself from his zombie sister. I wanted to see him die... But you never get to know what happens to him!! He caused the deaths of Luke (and possibly Bonnie) and, to an extent, Kenny/Jane.
